Guide to Uninterruptible Power Supplies for Your Home Office

A typical day in the office will expose us to dozens of devices powered by a power supply, which includes computers, airconditioning units, photocopying machines, and many more. These electronic machines require a power supply to keep going and do its job, and thankfully, company owners have them all covered. 

But what if one day you were required to work at home? In some unusual cases that would require us to stay home, like the emergence of a virus threat, most companies would give us an option to work from the comfort of our home.

The idea would be excellent since you won’t have to wake up early and get caught in the traffic. You have your comfortable chair, your television, snacks in the fridge, and other stuff that would make your stay at home more exciting. 

However, working from home would need to consider different factors. Keep in mind that your computer and internet router, which are the most vital devices you need, runs in electricity. Meaning to say, you have to make sure that your power supply is stable because a sudden power outage would become a nightmare if you’re at work. 

Imagine you’re working on an important file that you need to submit or having a video conference with clients, then you suddenly had a power outage. This incident could have a significant impact on your job or, moreover, it might cost you your job. In such cases, what we need is an Uninterruptible Power Supply, which could avoid the hassle of a power outage. 

What is an Uninterruptible Power Supply (UPS)?

Also known as UPS, this technology would help us to have a better work office. It is a battery backup power system that could save your machines from harm. In case of a sudden power outage, UPS will supply power to your device enough for it shut down properly. 

This device is perfect if you’re working with a desktop computer because, unlike laptops, desktop computers don’t have a backup power supply. With this said, UPS could save your desktop computers from damages, as well as data loss.

In an occurrence of a sudden power outage, your device’s power supply will immediately switch over to UPS backup power to keep the machine running smoothly. The capacity and efficiency of the UPS system depend on the unit. 

In this article, we will dig deeper and learn more about the different types of UPS systems and other information that we need to know about UPS.

Three Types of UPS System

UPS has three main types, and these have unique functions that could vary its efficiency, durability, and design depending on how or where you are going to use them.

  • Standby UPS Unit – The Standby UPS is a backup power source. From the name itself, it’s only on standby and waits for the main power supply to drop. Once a sudden power drop occurred, that’s when the device will automatically switch over to the backup battery power. 
  • Line-Interactive UPSThis UPS unit is more of an upgrade to the Standby UPS. It has a similar design with Standby UPS. The only difference would be the special transformer included in this system, making it more efficient when it comes to unstable power supplies.
  • Online UPS Unit This unit is the best among all types of UPS systems and also the most pricey. The online UPS works like a filter that screens the power that comes from the primary power source. The incoming A/C power goes to the UPS unit gets converted to D/C, conditioning the power while inside the machine, and then turned back to A/C when it exits the unit. This unit doesn’t have to switch from A/C to D/C during power failures. One reason is that it bridges the main power to the device.

Common Power Problems

There are different known power problems that a consumer might experience. These problems have different effects that could harm household devices. Here are the most common power problems:

  • Surge is a sudden burst of electricity. A lightning strike is the most common cause of electrical surges. This occurrence could potentially damage affected electrical devices.
  • Blackout is a total power outage and could last for days or weeks. Blackout is frequent during the rainy seasons, especially when there is a typhoon.
  • Brownout is somehow similar to blackout, although it is only a drop in voltage. During severe weather conditions, power companies might lower electrical voltage to avoid a blackout. With low voltage, consumers might still experience sudden power outages, usually lasts for a couple of minutes, and could extend to hours.
  • Voltage Sags are similar brownouts. It occurs when having low voltages; however, it only lasts for a few seconds.
  • Overvoltage is the rise of voltage for a more extended period. Unlike electrical surges, this lasts longer and a bit weaker.
  • Frequency Noise, or also known as line noise, could potentially corrupt data through the interference of stray electromagnetic signals.
  • Frequency Variation is an unusual case of power problems since it usually occurs during the power supply is unstable. 
  • Harmonic Distortion is a change in electrical signals on a power supply.
